Summary The mafia on the idyllic Lake Constance? Together with her Swiss colleague, Captain Aubry, Nele is investigating organized crime at full speed after two water police officers were murdered. The first clue leads to the Italian shoe dealer Pucci, who is said to belong to the Calabrian mafia. But this is only the entrance to a "silk road" skillfully spun across Lake Constance by members of the 'Ndrangheta living in Constance. This was where goods and wanted mafiosi could be smuggled from Switzerland to Germany under the eyes of corrupt officials. When the head of the Konstanz Criminal Investigation Department, Gregor Heitmann, gets involved, it is clear that there must be other moles on the police side. Is Nele's friend Adrian Aubry one of them? He desperately protests his innocence. But the clues lead to him. When the only witness who could supposedly exonerate him, his boss Rita Neuhaus, is found shot dead - Aubry's fingerprints are found on the murder weapon - his game is over. Nele asks herself desperately: Have I fallen for a brutal Mafioso?
